The next number the Machine dispenses to Finch and the team belongs to Cyrus Wells, a custodian. His current blue collar job belies the fact that he has an MBA and was once a multimillionaire. What they also quickly learn is that the person who may figuratively pull the trigger on Cyrus, the target, is Root. Finch learns directly from Root that she has her own Machine-driven mission with Cyrus, her tasks (unlike Finch's) are laid out for her by the Machine immediately before she is to carry them out. All Root knows is that her overall goal is to protect the Machine, most specifically now from a competing Machine, namely Samaritan, which is close to being functional. Finch and Root will have to figure out if their Machine-driven tasks are incompatible, especially as Root has demonstrated in the past that the death of someone like Cyrus is acceptable collateral damage. They both have to figure out who truly is after Cyrus and what his role in getting Samaritan functional is. Root also ... Written by Huggo

Detective Lionel Fusco: Hey, nice try, Cocoa Puffs. There's no way I'm letting him leave with you.
Root: I understand. But there are things you don't know. For starters, Cyrus is currently wanted by not one but two very dangerous organizations. And you have no idea that there are currently 27 people en route to this location, the closest of whom is carrying two concealed firearms and a push dagger he used to kill three people in Dubai last month - one of them just for fun.

The writers launch Acker into the air ... and she flies
23 March 2015 | by (North America) – See all my reviews

In many ways the episode I was waiting for -- great fun.

The real backstory -- not the one in the script -- is that as this is written (spring 2015) there are in my view two dramas in production where the writing team is barking mad and unafraid of taking chances.

They are in no special order POI and Banshee.

And the above was a compliment I think this episode is important because the writers having long since thrown away the predictable but reliable Harold-Reese-Machine arc (how many shows do that?) just keeping trying stuff.

Here they gave Acker room to take over the whole episode (if she wanted to, and it seems she did). She steals it.

In my reviews I try to emphasize the "fun" factor and the "connection" factor because unlike theatrical releases TV makes you suffer through commercials to get to the good stuff, so you the viewer deserve a payoff And this episode delivers one
